Best Speaker for a reflective room ?

I doubt the room will ever sound like you hope it will. I have found out that equipment cannot erase room problems no matter how much money is spent. Who knows? Maybe it will sound good.

Thanks for everyone's help.  I know it isn't ideal.  I had tried ohm in my house up north in a room with similar characteristics and an even higher ceiling - they were lost.  I probably needed to go with larger units.  Thanks for the input everyone.  There are a few suggestions I haven't considered yet and will look into them.

With the WAF and other constraints, sounds like a few sets of  headphones and headphone DACs and Amps are in order. 😁

Despite years of really trying anything by Klipsch make my ears bleed, never, ever, put them in a 'bright' room unless you are already deaf above 12 Khz. Interestingly in one of my "bright rooms" omni directional speakers sounded the best, Ohm Walsh, Sonab OA 14's, and similar.  However neither worked well in my primary listening room. I even tried DSP, still no joy with Klipsch. Try even simple room treatment, bean bags, large soft chair, great for listening as well, curtains, artwork without glass, wall hangings, if you can leave the door open, try anything, if it's a bedroom, fill the wardrobe with closed and open the doors, you may just get a surprise.

It’s a rather large room.  Perhaps you can have a relatively near field system using omnis planted near the center of the room.
